functions(maybe others ?).

Hello,
When I clone this code and compile it, I get the following error:

LINK : fatal error LNK1104: cannot open file 'LLVM.lib'
Error: linker exited with status 1104
Error C:\D\dmd2\windows\bin64\dmd.exe failed with exit code 1.

I use ldc2, version: 1.33.0-beta1.

For example on windows there's no way official way buiding llvm as a shared library.

I made some change to your example for a simple sum function:

sum(10, 25) = 35

but it turns out

sum(10, 25) = 10

seems that the second parameter is not passed in when calling LLVMRunFunction.
Can you help me identify the issue? this code is almost identical to a C version code I found at https://github.com/paulsmith/getting-started-llvm-c-api, which works fine.

    LLVMSetFunctionCallConv(f, LLVMCCallConv);

    auto p1 = LLVMGetParam(f, 0);
    auto p2 = LLVMGetParam(f, 1);

https://github.com/Calrama/llvm-d/blob/master/source/llvm/functions.d#LC1488 conflicts with the declaration two lines below it. That causes a build failure when compiled with ldc 1.1.0 and llvm >= 3.7.0.

The C API isn't currently configured to allow linking to recent LLVM releases (i.e. 3.7). I can add the new versions (at least in versions.d) and submit a pull request if you'd like.

There has been quite a few version releases since 7.0.0, and i'm getting missing symbol errors with LLVM 7.0.1 (which is in the arch linux repos)

Could llvm-d be updated to support newer LLVM releases?

Hi!

Are there any plans to support newer versions of LLVM? Specifically I'm hoping for v10.0.1, but even v9 would be great.

Hi Moritz,

I'd like to use your library to learn about LLVM and make a small language of my own. I tried llvm-d on dub but failed: the new dub system requires that a library needs to have a release tag.

Do you plan to update this library to make it work in the newest version of dub/dmd?

Hi!

Great job with this project! Is the binding complete? I've been trying to translate this line of code into D for about an hour now with no luck. Any ideas? Sorry for creating an issue, did not know where to ask for support.

Thanks for the work!

It looks like there's a small bug.
import llvm.all; //public imports llvm.d.llvm_c;
//which doesn't work as shown...

I feel like it should instead import llvm.c.all; since everything compiles nicely that way.

Thank you

Hello.
I have a problem with the load function - it just doesn't find libLLVM.so .
I even moved libLLVM.so to the project folder - nothing works.

I'm getting the following build error whenever I run dub or dub build:

Error executing command build:
Invalid SemVer format: LLVM_3_6_2

My dub.json file:

{
    "name": "project",
    "description": "A minimal D application.",
    "copyright": "Copyright © 2016, bennetleff",
    "authors": ["bennetleff"],
    "dependencies": {
        "llvm-d": "~>1.0.0",
    },
    "version": "LLVM_3_6_2",
}

Am I specifying the LLVM version wrong?

I have to manually add lflags after libs in dub.json

"libs": ["LLVM"],
"lflags": ["-L/usr/lib/llvm-3.8/lib/"]

for it to compile.

In release mode the build freezes and over time uses more and more memory (over 2 GB before i stopped it). Is that normal?

Right Here.

The version on my system is simply libLLVM-3.3.so.1.

Maybe need some way to explicitly choose the name?
